Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
The Kata description explicitely states: "The start time will always be before the end time."
Also AM/PM has nothing to do with this. "Time is stored internally as the number of seconds with fraction since the Epoch, January 1, 1970 00:00 UTC"
